The Jazz point guard dressed slowly, and softly discussed the final plays of the game with Marvin Williams: Why he short-armed the 3-pointer with seven seconds left, why he didn't dribble back out before missing a layup with 21 seconds left.
Not that frustrating?
Don't bother trying to sell that idea to Mo Williams, who took the loss in what could have been the Jazz's signature win as a personal insult.
"I just wish I could have closed it out for us," he said. "But, I'll take and make that shot or miss it time and time again, if I'm in the position. I'll shoot it with confidence. I have a lot of confidence in my ability."
Late Wednesday, Williams took accountability for the loss on Twitter, saying he made a "couple bad decisions."
Millsap had his second strong outing, following up his 34-point night Monday in Toronto with a team-high 20 points and 12 rebounds. Four other Jazz players reached double figures, including Mo Williams, who finished with 14. However, the point guard spent the rest of the night wondering why he couldn't make one more basket.
Williams had the ball with 32 seconds left, but rather than play for a 2-for-1 situation, held on to the ball. The result was the missed layup he replayed in his mind, over and over.
"Playing back the first shot with my head," he said. "I don't know. I think … I don't know. It felt like I was moving too fast for some reason. The play we drew up kind of broke down."
The Jazz sustained several runs by the Celtics, who got help from all corners. Paul Pierce led all scorers with 23 points, but both Leandro Barbosa and Jeff Green added 16 points off the bench for Boston.
The Celtics led by six points with 7:09 remaining, but the Jazz rallied. An 18-footer by Jefferson with 1:55 left in the fourth tied the game at 93, and momentum seemed to be in the Jazz's favor.
But they would not score again.
"Boston is tough to score on when they set up their defense," said Jefferson, who played for the Celtics from 2004-07. "I think for the most part we still had a chance to win; that's all you can ask for. It's a great team on their own floor. Just missed some big shots that really could have helped us."
The Jazz dipped below .500 after evening their record with a triple-overtime victory Monday in Toronto. However, with two games remaining on this four-game East Coast road trip, the more concerning trend is that each of those losses came away from EnergySolutions Arena. Corbin insists that the Jazz, who are 3-0 at home, are taking these losses and channeling them toward future success.
"This is a good team," he said of the Celtics, "and this is a good lesson for us to learn how to play on the road."
